A. The kinetic energy of the food particles increased, causing the food temperature to rise.

B. The thermal energy of the food increased

Explanation:

The grilling of the meat increased the thermal energy which cause the kinetic energy of the food particles to increase thereby causing the temperature of the food to rise.

Heat is a form of energy known as thermal energy. It results from the difference in temperature between two bodies.

When a body is heated, the particles of the medium if solid as in the case of the meat begins to vibrate about their fixed point.

Temperature is directly proportional the average kinetic energy of a particle and so the particles gain more kinetic energy.
